SHEET 1 [IF 2 STA PATENTED DEC 8 I976 SHEET 2 [1F 2 CUTTING AND DISPOSING APPARATUS FOR IRON SCRAPS AND THE LIKE The present invention relates to an apparatus for disposing of waste articles ranging in size from such large article as a car body to small articles such as a gasoline drum can or an iron pipe, in which such waste articles are crushed flatways and further cut into pieces. The primary object of the invention is to dispose of a large amount of scrap iron at one time and at extremely high efficiency by a positive operation.

A preferred embodiment of the invention is shown in the accompanying drawings, in which FIG. l is a front view of an apparatus of the present invention, and FIG. 2 is a perspective view thereof.

In the conventionally known apparatuses of this type, a cutting and crushing block ispivotally secured at one end thereof to the machine shell which is opened at the upper part and provided with blades at both side edges, said cutting and crushing block being so arranged as to be vertically movable from one end of the shell to the other end while describing an arcuate track, and waste articles or iron scraps are stuffed in the shell and therein subjected to the cutting and crushing block to be thereby crushed and cut into pieces of a size convenient for disposal thereof. In such conventional apparatuses, however, waste articles or iron scraps loaded in the shell are forcibly pressed and displaced in the direction opposite to the pivotally secured point of the cutting and crushing block by this arcuately descending block, which inevitably results in producing such parts that stay out of the accessible range of the blades and are left uncut, so that the cutting operation proves to be extremely inefficient.

The present invention is designed to eliminate these defects and is characterized by providing a pair of cutting-crushing blocks which vertically move symmetrically, each describing a circular arc, from both ends of the shell opened at the upper part towards the center of said opening.

In the following will be discussed an embodiment of the present invention with reference to the drawings. In the drawings in general, 1 denotes a shell which is opened at the upper part thereof and is provided with blades 2 disposed along both side edges thereof. 3, 3 are a pair of struts erected at both sides of the shell, and the cutting-crushing blocks 5, 5 having blades 4, 4' are pivotally secured to the lower part of said struts by means of pivots 6, 6. 7, 7' designate the hydraulic cylinders which are pivotally secured to the upper part of the struts 3, 3' by means of pivots 8, 8, respectively. Piston rods 9, 9' which reciprocate inside of said cylinders are coupled to said cutting-crushing blocks 5, 5, respectively.

Said hydraulic cylinders are also connected to an oil reservoir (not shown) through flexible pipes 10, 10', respectively. It will also be noted that one 5 of said cutting-crushing blocks 5, 5' has in its center an elongated portion 11 which extends towards the other block 5, while the other block 5 has a recessed portion 12 in which said extended portion 11 may be snugly fitted. To said extended portion and said recessed portion are connected the free ends of longitudinally extending blades l3, 14', respectively. 14 is a space formed in the inside of the shell, and into this space is thrust a push rod 15 from one side of the shell. 16 is a slicing mechanism mounted at the opposite side of the shell and provided with a blade 17 which vertically moves towards the end of the space 14.

In practice of the present apparatus having the above described construction, a used car body or other waste articles or iron scraps are fed into the space 14 in the shell 1 and the hydraulic pump (including cylinders 7, 7 and piston rods 9, 9) is actuated, whereby the cutting-crushing blocks 5, 5 start to descend from the solid-line position shown in FIG. 1 and turn around pivots 6, 6', respectively, while respectively describing symmetrically circular arcs towards the center of the shell 1, so that waste articles or iron scraps fed in the shell are crushed by a powerful leverage produced by cylinders 7, 7, piston rods 9, 9' and cutting-crushing blocks 5, 5'. First of all, the parts jutted out of shell are cut out by blades 2 at both sides of the shell and the entire junk is stuffed in the space 14 of the shell. When said pair of cutting-crushing blocks reach a position where they are horizontally sustained with respect to each other in a manner as shown by the dotted lines in FIG. 1, waste articles, iron scraps or the like in the shell are now cut into pieces by the blades 4 of the blocks 5, 5' (said blades 4 are preferably provided in as many number as possible on the block surface and disposed lengthwise or crosswise with a suitable space between each adjoining blades). In this case, it will be noted that the pair of blocks 5, 5 descending symmetrically to each other while describing a circular arc act to press the junk toward the center of the space 14, so that the junk, without moving out of the shell, is cut into pieces in a perfect manner.

It should also be noted that an extended portion 11 of one of the blocks is securely fitted in a recessed portion 12 of the other in the center of said blocks .5, 5', so that when both blocks take a horizontal position, no space is formed. Hence, there are produced no such parts that are left uncut.

These iron scraps or other junks which were crushed and cut in the space 14 in the manner described above are then pushed by a push rod 15 from one end of the space towards the other end, and the moment they are extruded out of the shell, they are sliced into a desired length or width by a vertically moving blade 17 of a slicing mechanism 16.

Said push rod 15 and slicing mechanism are automatically operated at suitable time intervals by a known interlocking mechanism, and by adjusting this time intervals, the extruded iron scraps may be cut into lumps of a desired size.

Iclaim:

1. An apparatus for cutting, crushing, and disposing of iron scrap and the like, comprising an elongated shell of channelshaped configuration having a hollow, upwardly directed interior and terminating in a pair of opposed longitudinally extending upper side edges, a pair of elongated cutting blades respectively fixed to and extending along said side edges of said shell, a pair of struts situated at each side of said shell with the pair at one side alined with the pair at the other side, a pair of horizontal pivots extending between and carried by said struts, a pair of cutting-crushing bloclks respectively supported for swinging movement by said pivots from upper rest positions spaced from each other downwardly toward each other while approaching the hollow interior of said shell, a pair of piston rods respectively coupled to said blocks, hydraulic cylinders respectively coacting with said rods for providing through the latter crushing force supplied to said blocks, a push rod in said shell for movement from one toward the other end of said shell to displace crushed and cut treated material therein longitudinally therealong, and a vertically movable blade situated at said other end of said shell for cutting vertically through the treated material.

2. An apparatus for cutting, crushing and disposing of iron scrap and the like, comprising an elongated shell of channelshaped configuration having a hollow upwardly directed interior, and a pair of cutting-crushing blocks situated over the hollow interior of said shell and supported for swinging movement downwardly toward the hollow interior of said shell while approaching each other, said blocks respectively terminating in free ends which approach each other as said blocks swing downwardly toward the hollow interior of said shell, the free end of one of said blocks being elongated, extending transversely across the hollow interior of the shell, and having an extended portion while the free end of the other of said blocks is also elongated and extends transversely across the hollow interior of said shell with the latter free end being formed with a recess which snugly receives said extended portion as said blocks swing downwardly toward the hollow interior of said shell, and a plurality of cutting blades carried by said blocks and including blades fixed to said free ends of said blocks and extending therefrom longitudinally along said blocks.
